Here is my situation, I have a router R1 whose external IP address is 22.214.171.124. I have another router R2 whose external IP address is 126.96.36.199.
I am running eBGP on R1 and R2. However, I cannot ping R2 from R1 and R1 from R2. How can I make them to ping each other? I know that they are in a different subnet. But, this can be a practical case where I don't want to force the external IP address to match the subnet of the other router interface.
